120 years ago, in preparation for the coming doom, mankind began an exodus to the manmade satellites in outer space. But the "Day of Judgment" arrived even before half the population had escaped to space. The shift in the tectonic plate caused the shape of the Pacific Ocean to change and a new continent was created. After 100 years, the only inhabitable areas were limited to the area around the new Pacific Ocean and the new continent. New nations were founded on this continent and mankind began rebuilding their lives. In the midst of rebuilding, "Gaiathyst" a mineral which releases an energy similar to gravity was discovered as a new source of endless energy. The nations began to war with each other for domination, but conventional weapons were found useless due to the influence of the Gaiathyst. To fight under these conditions, the power suits used to mine Gaiathyst were improved for combat. But the "Gaiathyst War" came to an abrupt end by the invading forces of the Zodgierra Empire from outer space. After conquering the nations, Emperor ZORR creates the "SAP", a super gravity producing device. Orbiting over the new continent, the super gravity of the device, prohibits beings not wearing a power suit to exist under it. Protected by the super gravity, ZORR commands his empire from a tower under the SAP. A few brave make a stand to defeat ZORR. They are the true Heroes.

Dual Heroes was developed by Produce! It was the first fighting game to use analog controls. Hudson Soft programmed multiple AIs for each character, in an effort to imitate different players controlling the character on different occasions, and thereby make the game's single-player mode more closely emulate the multiplayer fighting game experience. The game was shown at E3 1997, being 70% completed. A complete build was later shown at the 1997 Nintendo Space World.
